Subject [jira] Created: (AXIS2C-1491) memory leak at axis2_dep_engine_get_svc_dir
Date Tue, 10 Aug 2010 18:57:16 GMT
memory leak at axis2_dep_engine_get_svc_dir

                 Key: AXIS2C-1491
             Project: Axis2-C
          Issue Type: Bug
          Components: core/deployment
    Affects Versions: 1.6.0
         Environment: debian Linux
            Reporter: H.Wang

I see the following memory leaks from the axis2c client stub code. When the file_flag is set,
  "repos_path = axis2_dep_engine_get_svc_dir (dep_engine, env);" allocates new memory, but
at nowhere this memory is freed. It appears that this leak occurs when AXIS2C_HOME points
to the axis2.xml file instead of the directory that holds axis2c.xml. We set AXIS2C_HOME to
the axis2.xml file because we have both axis2c server component and client sub on the same
system, and they need to point to different axis2c.xml files.

The leak comes from the following code,
AXIS2_EXTERN axis2_status_t AXIS2_CALL
    axis2_arch_reader_t * arch_reader,
    const axutil_env_t * env,
    axis2_char_t * file_name,
    struct axis2_dep_engine * dep_engine,
    axis2_svc_grp_t * svc_grp)
    axis2_status_t status = AXIS2_FAILURE;
    axis2_char_t *svc_grp_xml = NULL;
    axis2_char_t *repos_path = NULL;
    axis2_bool_t file_flag = AXIS2_FALSE;
    AXIS2_PARAM_CHECK(env->error, file_name, AXIS2_FAILURE);
    AXIS2_PARAM_CHECK(env->error, dep_engine, AXIS2_FAILURE);
    AXIS2_PARAM_CHECK(env->error, svc_grp, AXIS2_FAILURE);

    file_flag = axis2_dep_engine_get_file_flag (dep_engine, env);

    if (!file_flag)

        repos_path = axis2_dep_engine_get_repos_path(dep_engine, env);

        svc_grp_xml = axutil_strcat(env, repos_path, AXIS2_PATH_SEP_STR,
                                 AXIS2_SERVICE_FOLDER, AXIS2_PATH_SEP_STR,
                                 file_name, AXIS2_PATH_SEP_STR, AXIS2_SVC_XML,
        repos_path = axis2_dep_engine_get_svc_dir (dep_engine, env);
        svc_grp_xml = axutil_strcat (env, repos_path, AXIS2_PATH_SEP_STR,
                                  file_name, AXIS2_PATH_SEP_STR, AXIS2_SVC_XML,
